  • Seroquel XR Overview

    Seroquel XR 300mg is used to treat certain mental/mood conditions (such as schizophrenia, bipolar disorder, sudden episodes of mania or depression associated with bipolar disorder). It is also used with other medications to treat depression. Quetiapine is known as an anti-psychotic drug (atypical type). It works by helping to restore the balance of certain natural substances (neurotransmitters) in the brain. Seroquel XR 300mg can decrease hallucinations and improve your concentration. It helps you to think more clearly and positively about yourself, feel less nervous, and take a more active part in everyday life. It may also improve your mood, sleep, appetite, and energy level. Quetiapine can help prevent severe mood swings or decrease how often mood swings occur.

  • Seroquel XR Warnings

    There may be a slightly increased risk of serious, possibly fatal side effects (such as stroke, heart failure, fast/irregular heartbeat, pneumonia) when Seroquel XR 300mg is used by older adults with dementia. Seroquel XR 300mg is not approved for the treatment of dementia-related behavior problems. Discuss the risks and benefits of Seroquel XR 300mg, as well as other effective and possibly safer treatments for dementia-related behavior problems, with the doctor. If you are using quetiapine in combination with other medication to treat depression, also carefully read the drug information for the other medication. Quetiapine sustained-release is used to treat certain mental/mood disorders (such as schizophrenia, bipolar disorder, sudden episodes of mania or depression associated with bipolar disorder). It is also used with other medications to treat depression. Drugs used to treat depression can help prevent suicidal thoughts/attempts and provide other important benefits. However, studies have shown that a small number of people (especially people younger than 25) who take drugs to treat depression may experience worsening depression, other mental/mood symptoms, or suicidal thoughts/attempts. It is very important to talk with the doctor about the risks and benefits of drugs used to treat depression (especially for people younger than 25), even if treatment is not for a mental/mood condition. Tell the doctor right away if you notice worsening depression/other psychiatric conditions, unusual behavior changes (including possible suicidal thoughts/attempts), or other mental/mood changes (including new/worsening anxiety, panic attacks, trouble sleeping, irritability, hostile/angry feelings, impulsive actions, severe restlessness, very rapid speech). Be especially watchful for these symptoms when a new drug to treat depression is started or when the dose is changed. Seroquel XR 300mg is not approved for use in children under 10 years old.

  • How to Use Seroquel XR

    Read the Medication Guide and, if available, the Patient Information Leaflet provided by your pharmacist before you start using quetiapine and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take Seroquel XR 300mg by mouth as directed by your doctor, usually once daily in the evening without food or with a light meal. Swallow the tablets whole. Do not crush or chew the tablets. Doing so can release all of the drug at once, increasing the risk of side effects.

Take Seroquel XR 300mg regularly to get the most benefit from it. To help you remember, take it at the same time each day.

Quetiapine may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away. The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using quetiapine,certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death). Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation.

Since untreated mental/mood problems (such as schizophrenia, bipolar disorder, depression) can be a serious condition, do not stop taking Seroquel XR 300mg unless directed by your doctor.
